The molecular systematics of 337 strains of basidiomycetous yeasts and yeast-like fungi, representing 230 species in 18 anamorphic and 24 teleomorphic genera, was determined by sequence analysis of the D1/D2 region of the large-subunit rDNA. The data were compared with published sequences of other basidiomycetous fungi. The results demonstrated that the… (More)
Basidiomycetous yeasts in the Urediniomycetes and Hymenomycetes were examined by sequence analysis in two ribosomal DNA regions: the D1/D2 variable domains at the 5' end of the large subunit rRNA gene (D1/D2) and the internal transcribed spacers (ITS) 1 and 2. Four major lineages were recognized in each class: Microbotryum, Sporidiobolus, Erythrobasidium… (More)
Three species of yeasts are taxonomically described for strains isolated from marine environments. Candida spencermartinsiae sp. nov. (type strain CBS 10894T =NRRL Y-48663T) and Candida taylorii sp. nov. (type strain CBS 8508T =NRRL Y-27213T) are anamorphic ascomycetous yeasts in a phylogenetic cluster of marine yeasts in the Debaryomyces/Lodderomyces clade… (More)
Mangrove forests inhabit the shoreline regions of tropical and subtropical marine habitats, where they are the basis of a multi-trophic level food web that drives the shellfish and fisheries industries. Yeasts, and other fungi, have significant roles in these ecosystems as they decompose plant organic material and serve as a food source for small… (More)
Yeast populations in the Shark River Slough of the Florida Everglades, USA, were examined during a 3-year period (2002–2005) at six locations ranging from fresh water marshes to marine mangroves. Seventy-four described species (33 ascomycetes and 41 basidiomycetes) and an approximately equal number of undescribed species were isolated during the course of… (More)
The V3 variable region of the large subunit rRNA was examined for nucleotide sequence signatures as potential taxonomic tools. Data are presented on 117 species, representing 23 genera of basidiomycetous yeasts. The results of nucleotide sequence alignments indicate that strains within species have identical base sequences and that species may differ from… (More)
The teleomorphic basidiomycetous yeast Xanthophyllomyces dendrorhous is important as a commercial source of astaxanthin, which is a component of feeds for mariculture. Phaffia rhodozyma is the anamorphic state of Xanthophyllomyces; however, there are conflicting reports in the literature concerning the presence of a sexual cycle in P. rhodozyma. The current… (More)
The validation of Sporidiobolus microsporus Higham, nom. nud. is based on phenotypic characterization and molecular sequence analysis of a partial region of the large sub-unit ribosomal DNA. The species is compared, based on phenotypic and molecular characteristics, with other species of Sporidiobolus and the closely related Rhodosporidium fluviale.
Based on similarities in basidial morphology and nucleotide sequences of the V3 variable region in the large sub-unit ribosomal RNA, the yeastLeucosporidium lari-marini is considered phylogenetically related to the genusCystofilobasidium. Therefore the new combinationCystofilobasidium lari-marini is proposed.
Sporobolomyces ruberrimus Yamasaki and Fujii nom. inval. is established as a distinct species by ribosomal-DNA base composition in the D1, D2 and ITS regions and by morphology. A Latin description is given to validate the name with CBS 7500 as the type strain.
